2 Claims.

This inventionrelates to hooks, and the present invention is concernedwith a hookof the type disclosed in Patent No. 1,237,885, granted to ,meunder date of August 21, 1917.

The present invention involves certain new and useful improvements overthe type of hook aforesaid, and has particular reference to improvedmeans for securing the hook closed and from becoming accidentallydetached from the work with which it may be engaged.

The invention together with its objects and advantages will be'bestunderstoodfrom a study of the following description taken in connectionwith the accompanyingdrawing, wherein:

Figure 1 is a side view of the hook with certain parts broken away andshown in section.

Figure 2 is a top plan view of the hook. Figure 3 is a sectional viewtaken substantially on'the line 33 of Figure 2, and 20 Figure 4 is afragmentary view of thesheath and sleeve constituting the free endconstruction of a keeper unit. 7

Referring to the drawing by reference numerals it will be seen that inthe preferred embodiment thereof the hook comprises a body I having anintegral bill 2. A clevis 3 is connected with the body I through themedium of a bolt and nut 4.

Further there is provided a keeper unit 5 which at one end is notched orrecessed as at 6 to receive the end of the body 1. remote from the bill2, and the keeper unit 5 is pivoted to the body I.

through the medium ofY the' aforementioned bolt At said slotted end thekeeper 5 is provided with a peripheral groove I I which accommodates alooking or retaining sleeve I2.

Sleeve l2 is'of a length slightly less than the length of the groove IIand is rotatable about the keeper 5 as an axis.

Sleeve I2 is provided with a notch I3 that is adapted to aline with theunderside of the slot -'1 in the keeper 5 so as to permit free passageof the bill 2 into and out of the slot 1.

With the bill 2 arranged in the slot 1 the same 7 is retained in saidslot against casual displacement by rotating the sleeve, 12' forpositioning the notch 13 in the sleeve out of alinement with the bottomside of the slot 1 or to the position shown in the drawing.

It is believed to be clearly apparent that with the sleeve in thementioned position a separation of the bill 2 and keeper 5 is positivelyprecluded.

To disengage the hook and keeper, it is only necessary to rotate thesleeve 12 to aline the notch 5 7 13 therein with the bottom of theslot 1. This leaves the bill 2 free to pass out of the slot throug thebottom side of the latter.

In conclusion and briefly stated, the hook embodying my inventioncomprises a body and a 10 belt. A keeper is pivoted to the body of ahook at one end of the hook remote from the bill, and is provided at itsfree end with a sheath for receiving the bill of the hook. Mounted onthe keeper, and rotatable about the axis of the keeper 15 is a sleeveadapted to retain the cell in the sheath. The sleeve is provided with anotch which is adapted to align with the open side of the sheath topermit movement of the bill into and out of the sheath.

It will thus be seen that I have provided a hook 'which is so equippedas to positively retain the hook engaged with the work such as the linkof .a chain, or the like, and that the means for re:

' taining the hook 'so positively engaged with the work has numerousadvantages over the hook shown in my aforementioned patent,'as will beclearly appreciated by those skilled in the art.

Having thus described the invention what is F claimed as new is:

V 1. A hook comprising a body and a bill, a keeper pivoted to the bodyof the hook at the end of the hook body remote from the bill, and saidkeeper at thefree end thereof being provided witha sheath for receivingthe bill, and a sleeve on said end of thekeeper and rotatable about thekeeper as an axis, said sleeve being engageable with the bill forretaining the latter within said i sheath, andsaid sleeve beingv alsoprovided with a notch adapted to aline with the open side of said sheathto. permit movement of the bill into and out of said sheath.

2. A hook comprising a body and a bill, a keeper pivoted to the bodyof'a hook at the end of the body'remote from the bill, and said keeperat 45 the free end thereof being provided'with a sheath 7 i ERICKERICKSEN.
